T at whom it may concern.-

Be it known that 1, JOHN J. HE'YS, of Lynn, in the county of Essex andState of Massachusetts, have invented new and useful Improvements inSole-Cuttin g Machines, which will, in connection with the accompanyingdrawings, be hereinafter fully described, and specifically defined inthe appended claims.

In said drawings, Figure 1 is a front elevation of so much of my machineas is requisite to show my present improvements and their mode ofoperation. Fig. 2 is an elevation taken at the right-hand side ofFig. 1. Fig. 3 is a top plan view of Fig. 1. Fig. 4: is a sectionalelevation, the section being taken as on line Z Z, Fig. 3, and the viewas from the righthand side of Figs. 1 and 3. Fig. 5 is a detachedvertical section taken as on line Y Y, Fig. 3, and viewed as from theright in that figure. Fig. 6 is a detached perspective view of thecutting-die as prepared for use in my improved machine. Fig. 7 is adetached perspective View of the follower and attached parts that coactwith the cuttingdie. Fig. Sis a detached elevation of the dieplate, thefollower, and coacting parts. Fig. 9 is a rear side elevation of thefinger-guard plate, the guide rod, and attached parts. Fig. 10 is anelevation of the die-plate and die when said plate is turned out to thefront as for adjustment of the die. Fig. 11 is a side elevation showingthe devices by which the treadle is locked when the die-plate is turnedout to the front for adjustment, as in Fig. 10, so that the machinecannot then be started. Fig. 12 is a top plan View of the treadle shownin Fig. 11.

The object of my invention is to furnish divers additions to andimprovements upon the sole-cutting machine patented to me by UnitedStates Letters Patent No. 521,793, dated June 26, 1894; and theinvention consists in the various improvements and the combinationsthereof that will be next here in described and then pointed out in theclaims.

Referring again to said drawings, A A represent the side frames of themachine, which are substantially the same as shown in my said formerpatent.

B B are reinforcing-rods inserted in the front portion of frames A,extended above said frames and supporting the top eross-girt D, held inplace by nuts C threaded on said rods in a well-known manner.

A rotarycutting-block His mounted in the machine, and it can be bothrotated and vertically reciprocated, to come in contact with thecutting-die 0, either by the means shown in my said former patent or byother means, as desired, the rotation and reciprocation of acutting-block being both old need be no further alluded to at this stageof the case.

E represents a lever driven as in my said former patent, or by othermeans, to actuate connector F, which is pivoted to and moves clearer Gback and forth on block H for removal of the sole and trimmingstherefrom after being cut thereon.

Girt D is formed with two downward projections a a, in which areinserted the pins 1 5,whieh pass through bosses formed upon dieplate b,so as to aid in supporting the same, the rear edge of said plate when inposition for use being supported by the catch-lever12, pivoted at 13upon a bracket secured to girt D, said lever engaging the lower side ofb, as shown in Fig. 4, and said lever being pressed into engagement withb by the spring 14, as shown. A small spindle 1 passes centrally throughgirt D, and a spring 2 seated in an enlarged chamber in the girt actsexpansively upon the enlarged head 3 of said spindle at its lower end,while the lock-nuts secured to the upper end of the spindle limit thedown ward action of the spring, as in said patent. In said head 3 ofsaid spindle is inserted a small plunger 4 upon which is arranged aspring 5 seated in head 3 to force at down constantly upon saddle q, asshown in Fig. '7, and for purpose to be explained.

The cutting-die c is adjusted and secured to the under side of plate Z)in the following manner: Two small pins ff, united by bar 1 are insertedin holes in plate I) so as to be forced in and drawn out by slightpressure, and when latch-lever 12 is released from plate Z) the latteris swung forward on pins so that pins f extend horizontally to the frontand the straighter or outer side of die 0 is then placed upon them, asshown in Fig. 10, and the notch or recess d in the top edge of the diebeing seated upon rib a, formed upon plate I), the die is then looked toplate I) by pins g that eXtend from brackets 7, secured by screws 8 toplate I). It is thus shown that die 0 is always secured to plate I) inexactly the same position in relation to its side and end cutting-edges,as the pins f and rib c constitute three bearings, said pins governingthe sidewise position of the die, while rib e entering notch d governsits lengthwise position, and hence the pins 9 should fit loosely in thedie, their only office being to force it against plate b. More thanthis, by properly positioning pins f, as shown, at the proper distancefrom the toe and heel part of die 0 all sizes of dies can be by the samemeans adjusted upon the same pins f without change of position of saidpins or notch cl and rib e. A spring (shown at 9, Fig. 8) bears at topagainst dieplate I) and its lower end bears against bar i that unitespins ff, and serves to force said pins outward, as shown in Fig. 8, whendie 0 is removed. Two rods n it pass loosely through plate Z) and havenuts 19 p threaded upon their upper ends, said nuts being interlocked insaddle q seated upon die-plate Z). Said rods at their lower ends aresecured in plate Z, which at or near its lineal center is formed withears through which pin m passes, and a follower j arranged in die 0 andbelow plate I is by its ear 7c loosely held upon said pin m. A pin tsecured in the end of plate Zpasses loosely through follower j, so thatwhen the latter is level said pin does not project from it, and a coiledspring w interposed between l and j on the opposite side of pin m tendsto force j downward and so cause pin 25 to project below follower j, theobject being that said pin will force the cut sole away from follower jand so cause it to fall away from said follower in case it should stickthereto.

Another important advantage of the pivoted follower j consists in thefact that when so arranged to rock upon pin 'm in all directions it willalways hear equally upon all parts of the sole that is being cut, andhence if, as often occurs, the sole is thicker at one end or side thanthe other the follower will bear with equal force upon all parts of it,which is of great importance in frictioning the sole when feeding itbeneath the cuttingdie.

Saddle q is constantly pressed down upon plate I) by a small plunger 4in the enlarged end of spindle y by spring 5 arranged above it, as shownin Fig. 4, and when the cuttingblock is forced upward till saddle qbears against spindle y then the force of spring 2 will resist thefurther upward movement of the moving parts, and it will force the soleout of die 0 when block ll decends.

The object of plunger 4, actuated by spring 5, is to hold the sole byfriction upon block 11 while being fed beneath follower j upon saidblock, and it prevents the movement of the sole beyond the distancerequired by the fingers 58, against which it bears, the force of spring5 being exerted upon buffers 20, secured upon rod 19, which buffers beardirectly upon the sole when it is being fed beneath the die.

Brackets 1.5 are secured to plate I), as shown in Fig. 4, and theguide-rod 19 is carried by curved links 13, connected with said brackets15 and said plate, (see Figs. 1 and 4,) and on said rods 19 are arrangedthe cushions 20, which prevent the operator from inserting his fingersbeneath said rod so as to be between the cutting-die c and thecutting-block II when the machine is in operation. A guardplate 21 issecured at its lower edge to guiderod 19 by the short fingers 10, whileat its up per edge a U-shaped piece 23 is united to it and has a screw22 threaded in it at top, as shown in Fig. 9. The arms of said piece 23stand away from plate 21 and pass upon each side of bolt 24 and are heldby the head of said bolt, as shown in Fig. 10, where said arms are shownin section, said screw 22 passing down to and being seated on the headof said bolt 24, as shown in Fig. 4. When it is desired to swingdie-plate b to the front, as shown by dotted lines in Fig. 4, the handleof latch-lever 12 is drawn to the front till the catch on the lower endof said lever is released from the die-plate, when by actuating arm 26,Figs. 2 and 11, rigidly mounted 011 shaft 25, a rigid arm 27 willthereby be depressed, and the rod 29, which at one end is pivoted to arm27 at 28, while its opposite end is pivoted at J to dieplate b, will bysaid means force said die-plate to swing on its pivots 45 to the front,as shown in Fig. 4;

and by the same motion rod 31 that is pivoted at 30 to arm 36, that ispivoted at 28, is swung forward upon its lower pivot 32, thereby causingits rigid lower arm 31 to swing rearward, thus forcing its hook 33 intocontact with catch 34, secured to treadle 35, thereby positively lockingthe same till the die-plate Z1 is returned to position with guardplate21 and the guide-rod 19 is in position to protect the fingers of theoperator, and the treadle is unlocked and liberated by the reverseaction of the parts with which it is connected, as just explained.

For the purpose of feeding the pieces of leather upon block H to be cutby die 0, I arrange a table, (shown at 37,) secured in place by bolts61, as shown in Figs. 2 and 3.

A toothed rack 38 is arranged to slide on.

table 37, and it is engaged by the correspondin gly-toothed arc of acircle 39, secured upon shaft 40, that is arranged and secured beneathtable 37. Said arc is vibrated back and forth by means of areciprocating lever 6, that may be driven as in my said former patent,or by any suitable means, and to this lever is pivoted rod 41, that atits respective ends is right and left hand screw-threaded to fit in hubsthat are pivoted to said lever and to arms 44, secured upon shaft 40, ahandwheel 42 being secured 011 said shaft-rod for IIO the purpose ofadjusting the length so that the feeding devices driven by shaft 40 canbe moved to the exact positions required at each end of their stroke, alever-nut 43 being arranged to be turned against the socketed end of rod41 to lock the rod when properly adjusted. A feed-slide 46 is securedupon and carried by rack 38, and at its outer end abolt 47 isinterlocked in said slide, and upon said bolt are secured by lever-nut65 the converging ends of connectors 48, the outer ends of which areengaged by pivots 51, which are seated in bushing 50 of fingers 52,arranged in oblique slots 4:9. (Shown in Fig. 3.) Said fingers 52 arethus at their rear ends pivoted to connectors 48, and they are alsopivoted to block 55, that moves in slot 56 of table 37 by screws 62,that pass through blocks 54:, seated in the outer arm of angle-levers53.

Two angle-levers 53 are pivoted at 64 to feed-slide 46,and their longerarms are toothed and interlock, as shown in Fig. 3, while their outerarms embrace blocks 54: and are by screws 62 attached to fingers 52. Acoiled spring 56, having its ends attached to the outer arms of levers53, tends constantly to draw said arms and fingers 52 inward, and hence,with slot 49, formed in table 37 to guide the left-hand finger 52, Fig.3, by means of block 55 sliding therein, both fingers 52 are governed bythe curvatures of said slot, and hence both of said fingers approachtoward and rccede from sole-blank 59 with equal rapidity.

Slot 57 upon its outer side is formed straight, while the inner sidecurves inward, and hence if sole-blank 59 is of a length to barely beadmitted between said fingers then the block 55 will follow the outerline of slot 57, while if said blanks are shorter and require saidfingers to move toward each other, in order to grip the end of theblank, said blocks follow the inner line of said slot till the sole isso gripped.

The office of adjustable fingers 58, mounted on feed-plate 46, is toserve as the means for movingblanks 5 9 into proper position on block IIfor cutting by the die 0, the endwise position of said blank beingobtained by the action of fingers 52, as already explained.

The gibs 60 are for the purpose of securing feed-slide 46 in place andto yet allow it a free reciprocating back-and-forth motion on table 37.

In practice the sides of the sole-leather are first cut into strips thewidth of which is practically the length of blank 59, then said stripsare cut into pieces or blanks, as shown at 59, and in this form are soldby leather-cutters to makers of shoes who then moisten the blanks andthen pass them back and forth through a rolling-machine to consolidatethe leather; and in this operation some are stretched more and someless, so that in the same bundle, of one size, there will be a variationof half an inch in length in some of the soles, and there will be acorresponding difference in the width of the soles from the same cause,and in order to utilize all that is possible of the larger soles thesmaller ones must be cut as close as possiblehence the object obtainedin having studs f arranged on the outer or straight side of the die 0and at alimited distance on each side of the widest part of the solerespectively, for positioning the die, and then arranging fingers 58 ina corresponding position to govern the sole when adjusting it on blockII preparatory to being cut as shown in Fig. 3; and for the same reasonit is requisite that fingers 52 have a self-adjustability in order toaccommodate themselves to the varying length of soles which they are tograsp and hold while being moved beneath the die.

The ends of fingers 52 and 58 are formed with a groove or recess 67 inwhich the ends of blank 59 are received and held when said fingers moveagainst it.

It will be observed that slots 49 are formed oblique to each other,their inner ends being farther to the rear than their outer ends, sothat when the free or inner ends of fingers 52 move toward blank 59 theywill by the same act move bodily to the front and when they move outwardthey will move bodily to the rear, and by this means the inner ends ofthe fingers will be practically at the center of the width of blank 59at all times.
